the crushing rolls for primary and secondary crushers are made up of a roll body in polygon design which is equipped with exchangeable crushing segments as a result of the specific geometry between roll body and crushing segment an optimum tight fit is achieved thus being able to stand up to the high crushing
roll crushers are a compression-type reduction crusher with a long history of success in a broad range of applications. the crushing chamber is formed by massive drums, revolving toward one another. the gap between the drums is adjustable, and the outer surface of the drum is composed of heavy manganese steel castings known as roll shells that are available with either a smooth or corrugated crushing
1 sugar mill roller shell 2.1 shaft - a round forged and machined steel bar on which cast iron shell is fitted. 2.2 shell seat - the fang straight portion of shaft on which the shell is fitted. 2.3 roller journal- the polished surface at both ends of shell-seat on which bearings are fitted.
controlled nips are crushing and hydraulic flow mark. water removal is aided by: • soft roll covers • large diameter press rolls • double felting • high sheet temperatures design considerations 1. low flow resistance: in flow-controlled nips, it is very important that flow resistance be minimized. typically, coarser batt deniers

the aurora dual rotor crusher features a dual shaft design that produces a higher throughput and smaller particles. rotor speed, rotor direction, cutter design, and screen opening size of our delumping machine are all factors to fine-tune the final product. our aurora models are ideal lump breaking equipment for pneumatic conveying or unloading.
normally the size of stone to be feeded is taken as 2” less than the width of machine nominated in the catalogue. in case of bigger size crusher, this figure goes up to 4”. the ideal ratio of jaw opening to the feed size is i:8. the power requirement may vary as per the hardness / quality of the rock to be crushed. parts list : main body; liver pin
we have made the following optimized design for the models such as pe400-600, pe250-750, pe600-900 which has been recognized after practical application. 1. deep chamber design high reduction ratio high crushing efficiency and fine crushing grain size. 2. improved rotary speed of eccentric shaft; high productive capacity.
numerical simulation of cj411 jaw crusher frame. in order to analyze the damage reason for cj411 jaw crusher in detail, the numerical simulation analysis of the frame was carried out by ansys software. due to the lack of detailed geometric parameters of the original design, the main dimensions of the rack were obtained by mapping the prototype of
a) primary crusher – the raw material from mines is processed first in primary crushers. the input of these crushers is relatively wider and the output products are coarser in size. example - jaw crusher, gyratory crusher, impact crushers, etc. b) secondary crusher- the crushed rocks from primary crusher are sent to these secondary

the capacity of the crusher is determined by its size. the gape determines the maximum size of material that can be accepted. maximum size that can be accepted into the crusher is approximately 80% of the gape. jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. gyratory crushers
crusher consists of a heavy cast-iron, or steel, shell/frame which includes in its lower part an actuating mechanism (eccentric and driving gears), and in its upper part a cone shaped crushing chamber, lined with wear resisting plates (concaves). construction detail and working of the crusher is as under.
cone crusher basics in 4 minutes. this is the starting point for understanding how cone crushers work – and how they can make your mine or quarry more productive. elsewhere on the site you can find detailed information about all aspects of crushing and screening, but to make sense of these it helps to understand the basics of cone crushing.
a crusher with coarse style liners would typically have a 6:1 reduction ratio. thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. reduction ratios of 8:1 may be possible in certain coarse crushing applications. fine liner configurations typically have reduction ratios of 4:1 to 6:1.
a combination of impact, shear, and compression are the forces necessary to perform the crushing and size reduction in a williams roll crusher. the material enters the roll crusher machine and is impacted by the roll as it rotates. then, as the material is pulled between a crushing plate or rolls, shear and compression forces act upon the material.
